The insulation limits are specified appropriately (esp. for personal protection)

7

The electrical tracing requirement and its limits are specified appropriately.

8

The wrapping and coating requirement and its limits are specified appropriately for u/g lines.

9

Minimum distance between welds is 50mm or five times the wall thickness whichever is greater, unless otherwise indicated in Project specifications.

10

Unions are provided in galvanized piping where threaded in-line items need to be removed for maintenance. Also, unions are provided at regular intervals (e.g. 24m) in straight pipe runs.

11

Full couplings are provided where applicable for small bore piping.

12

For piping below 2”, WN flanges are not directly welded to SW fittings. Also, PE pipes are not directly welded with swaged reducers (couplings are used in between).

13

Appropriate break-up flanges are provided in piping with internal lining and hot-dip galvanized piping (based on tub size). Spool configuration is made with one elbow or one tee only to ensure proper galvanizing.

14

Lifting lugs are provided for removable spools wherever required as per project requirements.

15

There is adequate clearance between pipe support and the adjacent piping component (e.g. flange, drain valve) to allow for flange bolt removal, valve operation, etc.

16

The valve stem orientation angle is indicated wherever the stem is not in the vertical and horizontal planes.
